IBM simulates cat's brain, humans are next
Almost exactly a year ago we noted DARPA pouring nearly $5 million into an IBM project to develop a computer capable of emulating the brain of a living creature. Having already modeled half of a mouse's brain, the researchers were at that time heading toward the more ambitious territory of feline intelligence, and today we can report on how far that cash injection and extra twelve months have gotten us. The first big announcement is that they have indeed succeeded in producing a computer simulation on par, in terms of complexity and scale, with a cat's brain. The second, perhaps more important, is that "jaw-dropping" progress has been made in the sophistication and detail level of human brain mapping. The reverse engineering of the brain is hoped to bring about new ways for building computers that mimic natural brain structures, an endeavor collectively termed as "cognitive computing." Read link will reveal more, and you can make your own cyborg jokes in the comments below.
Researchers tout progress in creating a brain on a chip
Mimicking the human brain has long been near the top of the list of dream projects for many a sci-fi-inspired scientist, and it looks like one team involved in the EU-supported FACETS initiative is now making some real, if still preliminary progress in the field. Apparently, they've built upon some recent mapping and modeling research and created an actual chip (or, more specifically a 20cm wafer), which could eventually contain a network of 200,000 neurons and 50 million synapses. That, the researchers say, will allow for them to take on larger scale neural computing work than has previously been possible, and could even lead to "practical neural computers" in as little as five years, which they say could be particularly helpful for things like internet search -- or, you know, commanding a massive robot army.[Thanks, Scott]
DARPA enlists IBM to build computer brain as smart as a cat
Researchers have long been trying to model actual brains in order to build a better computer "brain," and it looks like IBM is now getting a helping hand from none other than DARPA in its attempt to create one that it hopes will one day have the intelligence level of a cat. To that somewhat unnerving end, DARPA is pouring $4.9 million into a project that'll include five universities and scientists of all stripes, who will work together to create an artificial brain that behaves like a real one right down to the neuron level. As the BBC reports, the researchers are describing this latest initiative as a "180 degree shift in perspective" from previous efforts, as they're now seeking an algorithm first and problems second, as opposed to starting with an objective and devising an algorithm to achieve it. As for DARPA's ultimate goal, well, that's still a bit of a mystery, though let's just say we won't be surprised if future robots start to become very easily distracted.
